When I try to enter text into a text note, the input is completely bizarre. The background will sometimes flash black, or the line I'm editing will flash black and text over and over again.
I've looked around, but noone else seems to have this problem. This is on my Android tablet version 5.1.
Sorry: Example steps:
1) Open text note
2) Move cursor right
3) Wait
Expected: Just the flashing cursor
Seen: Flashing text AND cursor, with text flashing all black and momentary text on white background
